Macular SDD Subtypes
may have clinical significance in progression
Ribbon SDDs
Eyes with ribbon subtype have a 4.3 fold increased risk in developing GA24
Photoreceptors are disrupted in areas surrounding ribbon SDDs as well as in the area of SDDs themselves25
Dot SDDs
Eyes with dot subtype have a 2.5 fold increased risk of developing neovascular AMD24
Photoreceptors seem to be disrupted only in the areas that have dot SDDs, leaving adjacent photoreceptors unaffected25
